Two days of underground tests at Norwich's Plantation Garden, following concerns over sinkholes in the area, have been completed.

The historic garden, in Earlham Road, is currently closed to the public, with barriers preventing access, after sinkholes opened up at nearby properties owned by Tony Burlingham.

Mr Burlingham, who owns the MJB Hotel chain, closed off access to the site, although trustees, gardeners and security guards can enter by an alternative route.

Norwich City Council employed engineers to carry out testing of the gardens, which has been done.

Results of the tests, which included checking the driveway to Plantation House and whether a tunnel from a nearby sinkhole continues into the garden are now awaited.

The land is owned by the Preacher's Money Charity, leased to Norwich City Council and sublet to the Plantation Garden Preservation Trust.
